DTA143TU3HZGT106

Overview

The DTA143TU3HZGT106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It features a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes built-in bias resistors with typical values of R1 = 4.7 kΩ and R2 = 10 kΩ. Key electrical parameters include a minimum DC current gain (hFE) of 30 at -10 mA and -5 V, a power dissipation rating of 200 mW, and a maximum operating frequency of 250 MHz. The component is qualified under the AEC-Q101 automotive standard and supports a maximum junction temperature of +150°C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
• Qualified for automotive applications through compliance with the AEC-Q101 reliability standard.
• Provides high thermal stability with a maximum operating junction temperature of +150°C.

Applications

• Automotive electronic circuits requiring robust PNP switching capabilities.
• General-purpose inverter circuits utilizing built-in biasing for simplified layout.
• Low-power signal switching and logic interface applications.

Procurement Notes

Verify the specific suffix configuration against official ROHM documentation to ensure compatibility with target automotive or industrial specifications. Confirm that the SOT-323 package dimensions align with the intended PCB footprint. Check for any recent lifecycle status updates, as component availability may vary. Ensure that the AEC-Q101 qualification meets the specific grade requirements of the end application. Cross-reference the pinout diagram during integration to prevent orientation errors.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required for space-constrained designs. The SOT-323 package offers a small form factor suitable for dense PCB layouts. Consider the -50V voltage rating and -100mA current capacity to ensure adequate headroom for the load. The AEC-Q101 qualification makes it suitable for environments demanding higher reliability than standard commercial grades. Evaluate the 200mW power dissipation limit against thermal management constraints in the final assembly.

Part Context

This part belongs to the DTA143TU3HZG series of PNP digital transistors from ROHM Semiconductor. It is the complement to the NPN DTC143TU3HZGT106 within the same product family. Both devices share similar electrical characteristics and packaging but differ in polarity. The series is designed for general-purpose switching and inversion tasks in consumer and automotive electronics.

Replacement Considerations

Direct substitutes include the DTC143TU3HZGT106 for complementary NPN applications. Other compatible parts in the DTA143TU3 series may be considered if pinout and electrical ratings match. Verify package compatibility before substitution.
